FENCE RULES – DELAWARE (COUNTY), OHIO
OVERVIEW
Residential fences are permitted on private property within Delaware County, subject to local regulations. This page applies to properties in the unincorporated areas of Delaware County; incorporated municipalities and townships such as the City of Delaware, the City of Powell, Berlin Township, and Orange Township may regulate fences under their own ordinances or zoning resolutions.
Delaware County’s local fence rules appear primarily in the Delaware County Department of Building Safety Residential Fence Design Requirements, the Delaware County Building Code, the county’s residential permit materials, county zoning materials for Marlboro Township, Radnor Township, and Thompson Township, floodplain materials, and County Engineer right-of-way permit materials.
This page focuses on typical single-family residential fencing. If the jurisdiction’s adopted materials do not state a specific limit or requirement, this page notes that the code does not specify one.
Compiled From Delaware County Residential Fence Design Requirements, Delaware County Building Code, Residential Project Requirements, Exempt from Approval, Residential Building Permit Application, Pool Information, Delaware County Zoning Resolution for Marlboro, Radnor, and Thompson Townships, Flood Damage Prevention Regulations, Flood Hazard Area Development Permit Application, Delaware County Engineer right-of-way permit materials, and Delaware County Regional Planning Commission zoning and subdivision materials as of June 2026.
GOVERNANCE
Delaware County Department of Building Safety administers the county building-code framework for residential work and publishes the county’s residential fence approval requirements. The Delaware County Building Code incorporates the Ohio Building Code and the Residential Code of Ohio into the county’s local building-safety administration.
Delaware County does not publish a single countywide zoning rule that applies identically to every unincorporated residential property. The county zoning resolution applies to Marlboro Township, Radnor Township, and Thompson Township. Other townships and incorporated municipalities may administer their own zoning ordinances, zoning resolutions, zoning certificates, fence rules, or permit requirements.
The Delaware County Building Safety Office of Zoning Regulation and Delaware County Zoning Inspector administer the county zoning certificate process for county-zoned territory. The Delaware County Engineer administers county road right-of-way and easement permits. Delaware County floodplain and drainage review materials may apply where a fence project involves mapped flood hazard areas, grading, excavation, drainage, or related development activity.
PERMIT AND APPROVAL REQUIREMENTS
• Building Safety Approval: Delaware County treats fences less than 7 feet high as not regulated by the county building-safety fence approval process, unless the fence is part of a pool enclosure. Fences 7 feet or more in height require approval through the Delaware County Department of Building Safety.
• Fence Approval Submittals: For a fence requiring approval, Delaware County requires zoning from the township if applicable, a plot plan showing the proposed fence location on the property, and construction drawings showing a typical fence section, post spacing, fasteners, and design to resist wind loads.
• Taller Fence Review: Delaware County publishes prescriptive design information for fences from 7 feet up to 10 feet. Fences 10 feet 1 inch or above require design by a registered design professional.
• Zoning Review: Where township zoning applies, the fence approval packet must include zoning from the township if applicable. In Marlboro Township, Radnor Township, and Thompson Township, the county zoning certificate process is administered through the Delaware County Building Safety Office of Zoning Regulation and the Delaware County Zoning Inspector when a zoning certificate is required.
• Pool Enclosures: A fence that is part of a swimming pool, spa, or hot-tub enclosure is regulated separately from an ordinary yard fence. Delaware County pool materials require pool applications, township zoning permits, a plot plan showing the pool, utilities, fence, gates, and equipment, and pool-barrier review. For above-ground pools, a fence is required when the top of the pool sidewall at any location is less than 48 inches above finished grade.
• Floodplain Approval: Delaware County requires a flood hazard area development permit for development located wholly or partly within, or in contact with, an identified special flood hazard area. Fence-related work in a mapped flood hazard area may require floodplain review when it involves development, grading, filling, excavation, material storage, watercourse alteration, or similar site activity.
• Drainage and DESC Review: Delaware County building and residential permit materials may require drainage review, a drainage permit, or drainage, erosion, and sediment-control review when the project scope or site conditions trigger those programs.
• Right-of-Way and Easement Work: Work of any kind within a public road right-of-way or county or township road easement requires the applicable right-of-way permit or approval. This includes occupying the right-of-way or easement, ditch work, driveway-related work, utility work, and similar road-frontage activity.
FENCE PLACEMENT RULES
• Property-Line Placement: The ordinance does not state a setback requirement for standard residential fences from property lines; however, fences must be located entirely on the owner’s property and must not encroach into rights-of-way or easements.
• Plot Plan: For fences requiring Delaware County approval, the plot plan must show the proposed fence location on the property. Township zoning information must be included where applicable.
• Easements and Rights-of-Way: A fence must not be placed in a public road right-of-way, county or township road easement, drainage easement, utility easement, or similar restricted area unless the applicable approval allows that work.
• Road and Ditch Areas: Fence placement near county or township roads, ditches, culverts, driveways, storm sewers, or utility work may require review under Delaware County Engineer right-of-way or easement procedures.
• Flood Hazard Areas: Where the property is in a mapped special flood hazard area, Delaware County may require floodplain application materials showing floodplain or floodway limits, property boundaries, existing and proposed development, cut-and-fill areas, drainage facilities, and watercourse impacts.
• Pool Enclosures: When a fence is used as part of a pool enclosure, the pool plot plan must show the fence and gate locations, and the enclosure must be reviewed under the applicable pool-barrier requirements.
• Utility Safety: Ohio law requires notice through Ohio 811 / the protection service before excavation where Ohio’s underground utility protection law applies. For fence projects that involve digging, including fence post holes, notice must be given at least 2 working days, not including the day of notification, and not more than 16 calendar days before excavation begins. Working days exclude weekends and legal holidays. This statewide utility-notice requirement is separate from local fence permitting, zoning certificates, easement limits, right-of-way approvals, HOA restrictions, and other applicable requirements.
FENCE HEIGHT AND VISIBILITY RULES
• Local Maximum Height: Delaware County does not publish a maximum height for ordinary non-pool residential fences.
• Building Safety Threshold: Delaware County treats fences less than 7 feet high as not regulated by the county building-safety fence approval process unless the fence is part of a pool enclosure. Fences 7 feet or more require approval.
• Prescriptive and Designed Fences: Delaware County publishes prescriptive construction requirements for fences from 7 feet up to 10 feet. Fences 10 feet 1 inch or above require design by a registered design professional.
• Pool-Barrier Height Context: Delaware County pool materials state that an above-ground pool requires a fence when the top of the pool sidewall at any location is less than 48 inches above finished grade. This is a pool-barrier rule, not an ordinary yard-fence height limit.
• Visibility Rules: Delaware County does not publish a standalone residential fence sight-triangle or clear-vision height standard in the fence materials reviewed for this page. Road, driveway, ditch, right-of-way, easement, drainage, or township zoning requirements may still affect fence placement where those conditions apply.
MATERIAL AND CONSTRUCTION LIMITS
• Ordinary Residential Materials: Delaware County does not specify prohibited materials for ordinary non-pool residential fences in the fence materials reviewed for this page.
• Construction Drawings: For fences requiring approval, construction drawings must show a typical fence section, post spacing, fasteners, and design to resist wind loads.
• Prescriptive Fence Construction: For fences from 7 feet up to 10 feet, Delaware County’s prescriptive requirements include design for 115 mph wind load, 36-inch minimum post depth, 10-inch minimum post-hole diameter, 6-inch by 6-inch ACQ posts, and concrete placed to within 12 inches of the surface.
• Designed Fences: Fences 10 feet 1 inch or above require sealed construction drawings from a registered design professional.
• Pool Enclosures: Fences used as pool enclosures are reviewed under Delaware County’s pool-barrier framework. Delaware County’s pool materials reference 2021 ISPSC Section 305 for enclosure requirements, but the county materials reviewed for this page do not restate every technical pool-barrier detail.
• Finished Side, Opacity, and Orientation: Delaware County does not specify a finished-side rule, opacity requirement, or fence-orientation rule for ordinary non-pool residential fences in the fence materials reviewed for this page.
PRIVATE RESTRICTIONS
Private restrictions operate independently from Delaware County building, zoning, floodplain, drainage, and right-of-way requirements. HOAs, subdivision covenants, deed restrictions, private easements, architectural-review covenants, private boundary agreements, recorded partition-fence agreements, conservation easements, and other private agreements may be more restrictive than county rules.
Delaware County’s public permit materials do not state that private restrictions are enforced by the county as ordinary fence-code requirements. A property owner may need to satisfy both public requirements and any applicable private restrictions before installing a fence.
REVIEW AND ENFORCEMENT CONTEXT
Fence issues are typically reviewed during permit or approval review when required, and through complaint-based code enforcement. Examples include:
• A fence 7 feet or more in height requiring Delaware County Building Safety approval.
• A fence that is part of a pool enclosure, including pool-barrier review and pool final inspection.
• A proposed fence location that must be shown on a plot plan for county fence approval.
• Township zoning review where zoning from the township is applicable.
• County zoning certificate review in Marlboro Township, Radnor Township, and Thompson Township when the county zoning process applies.
• Fence work located in or affecting a mapped special flood hazard area, floodway, drainage area, watercourse, grading area, or similar regulated site condition.
• Fence work proposed within a public road right-of-way, road easement, ditch area, drainage easement, utility easement, driveway area, or County Engineer review area.
• A fence that conflicts with private easements, recorded restrictions, HOA covenants, subdivision restrictions, or other private agreements.
• Fence-post excavation requiring Ohio 811 / protection-service notice before digging.
